Yaw rate control method

A yaw rate control method utilizing differential braking of the vehicle wheels to impart a desired yaw moment on the vehicle, the method comprising the steps of: measuring the vehicle speed and steering angle (102); determining a desired yaw rate for the vehicle (106); determining an actual yaw rate...

Beschreibung
Zusammenfassung:	A yaw rate control method utilizing differential braking of the vehicle wheels to impart a desired yaw moment on the vehicle, the method comprising the steps of: measuring the vehicle speed and steering angle (102); determining a desired yaw rate for the vehicle (106); determining an actual yaw rate of the vehicle (107); determining a yaw rate error based a deviation of said actual yaw rate from said desired yaw rate (108); computing the desired yaw rate moment based on the determined yaw rate error (110); monitoring a plurality of vehicle parameters, and comparing said parameters to predetermined threshold values to determine if the vehicle is operating on a banked surface (128); forming a yaw rate offset based on the determined yaw rate error when it is determined that the vehicle is operating on a banked surface (124); and compensating the determined yaw rate error with said yaw rate offset to compensate the yaw rate control for yaw rate effects due to the banked surface (110).
